Genghis really does seem to be tweaking the news antennae today:

But does Genghis really deserve his conservative reputation? After all,
he had pretty radical ideas about social reform. When he conquered a
new tribe, it was his custom to liquidate the aristocracy and
assimilate the lower orders: "providing opportunities for the many and
not the few", as it were.

That liquidation of the aristocracy can be both explained and updated. What he was really doing was removing the extant power structure so that it would not serve as a resevoir of resentment to his new one. Of course, nowadays it is politicians not the aristocracy that hold power. So in this election season we could usefully remember his example. Kill all the politicians.
